Mass Effect: Dissension
The Citadel Council
The Citadel Council is the chief interstellar governing body of the Milky Way. The council exists by common consent of its constituent races. Most spacefaring races of the Milky Way are represented in Council politics in some way or other. While the “Council Races,” (those with representation on the Council itself) currently consist only of the Asari, Salarians, and Turians, a number of other species are deeply involved in Council politics. Races such as the Volus, Humans, Hanar, Elcor, and many more maintain embassies on the Citadel, and enjoy many of the same rights to representation, protection, and political enfranchisement as the Council races themselves. Most of these species are engaged in the process of securing spots on the council for themselves, a process which usually takes centuries of steadily gaining favor in the galactic political sphere.
The Council itself maintains exclusive jurisdiction over the Citadel and the surrounding space, and maintains its own police force, C-Sec, as well as its own limited navy for the purposes of regulation and self-defense. While it cannot exercise direct political control over the internal politics of any of its constituent species, the Council often functions as a mediating force, with the reputation of the Council and the voices of its constituents often being enough to regulate the galactic economy and bring arguing parties to the negotiating table. In extreme cases, the Council has been known to levy trade embargoes against hostile factions, and has, as in the case of the Skyllian Conflict, the right to declare certain regions of space open or closed to colonization, with the consensus of its members. All instances of first contact with newly-discovered sentient life are supposed to be handled by jointly-appointed diplomats from the Citadel Council.
The current representatives on the Citadel Council are:
